Jemma

Jemma had two PhD's and attended S.H.I.E.L.D's Academy of Science and Technology. Grant Ward attempted to kill both Jemma and Fitz. Fitz sacrificed himself to save Jemma, telling her that he loved her as he did so. Fitz survived with some brain damage, but their friendship was never the same due to the guilt Jemma felt for his sacrifice and because she did not reciprocate his feelings. Jemma was sucked into an obelisk that was a portal to another world.

Hermes

In Andy Weir's science fiction novel, The Martian, Hermes was the name of the space ship that transported humans between Earth and Mars. Hermes did not land on either planet, however. It launched from earth's orbit and remained in orbit of Mars while the crew transported to and from the surface in other vehicles.

In Futurama, Hermes Conrad was a bureaucrat and accountant at Planet Express. He loved being a bureaucrat and was often concerned about his grade. He was once a professional limboer. He had a wife named LaBarbara and a son named Dwight. He did not like Dr. Zoidberg.

Kenobi

In the Star Wars franchise, Obi-Wan Kenobi was a Jedi knight. He was Padawan to Qui-Gon Jinn, and later took Anakin Skywalker as his Padawan. He became a Jedi Master and served on the Jedi Council. After Anakin turned to the dark side and slaughtered the Jedi, Obi-Wan fought him, gravely wounding him and left him for dead. After Padmé died in childbirth, he took Luke Skywalker to Tatooine and watched over him. When Luke sought him out as an adult, he told Luke that Darth Vader killed his father, and taught him the ways of the Jedi. While on a mission to rescue Princess Leia, he was killed by Darth Vader.

There are many theories out there as to where Kenobi may have come from, but nothing definitive. I think that since you could shorten it to 'Ken', it makes it more wearable, but it might be better in the middle spot, or for a pet. Kenobi does not appear in the Social Security Administration's name database.
